Cautions	Li-Ion Batteries may explode if charged or discharged improperly. You must possess knowledge of electronic and understand how to handle Li-Ion battery. We reserve the right not to sell and void the warranty it you don't meet the above statement. You must use a protection IC (PCB) to keep battery from overcharge and over discharge Never solder directly onto the Li-Ion battery as overheat might cause battery to explode. If you are making a pack or need to solder batteries together, you need to get battery with tabs on it. You must solder to tabs instead directly onto the battery. Please read more safety warning about Li-Ion battery
Optional	For DIY, you may add tabs as an option at a little extra cost You must choose Our Smart Li-Ion Battery Charger and Battery holder to charge the Li-Ion cell with battery holder ( please charge one cell at a time, please charge more cells in series) . Never use conventional DC charger to recharge the Li-Ion battery.
